Reimbursement will depend on what exactly you are billing for? I am not a PMHNP but it sounds as if they will have you doing therapy in addition to assessment, diagnosis, treatment etc. I would assume a therapy only visit will be billed much differently than a mental health eval visit. I have worked in a integrated health system with both mental health and medical, we had a PMHNP and she did not do any therapy. We had social workers who did all the therapy with the clients. I would be sure to get specifics about what you willl be doing and what is expected before the job. I would also be sure you have a concrete salary agreement to protect yourself.
